The board of trustees for New Hampshire's university system plans to continue an in-state tuition freeze for another two years.

The University System of New Hampshire board endorsed the idea last week as it worked on the budget request it will finalize in September. If approved by the Legislature, it would be the first time an in-state student would pay the same tuition over four years at the University of New Hampshire, Keene State College, Plymouth State University and Granite State College.

Tuition was frozen for two years starting last fall, after the university system got a boost in state funding in 2013. Pamela Diamantis, chairwoman of the board of trustees, says continuing the freeze for two more years will provide tremendous relief for thousands of families.
